WE'B-SLITTING- MECHANISM.

Application filed July 26, 1906. Serial No. 327,815.

Be it known that I, WILLIAM A. PRINGLE, a citizen of the United States,residing at Niagara Falls, in the county of Niagara and State of NewYork, have invented certain new and useful Improvements in Web-SlittingMechanism, of which the following is a full, clear, and exactdescription, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to mechanism for cuttingwebs, and one of itsobjects is to provide improved mechanism of the above type for slittinga sheet of webbing into a plurality 'of strips.

Another object is to provide means for insuring an even feed of the webthrough the machine and for preventing the adjoining edges of the outstrips from lapping over one another when the same are being wound uponthe rewinding roller.

Other objects will be in part obvious and in part pointed outhereinafter.

The invention accordingly consists in the features of construction,-combinations of elements and arrangement of parts, which will beexemplified in-the mechanism hereinafter described and the scope of theapplication of which willjbe indicated in the following claims.

In the accompanying drawing, wherein is shown one, of the variouspossibleembodiments of my invention, Figure 1 1s a wow thereof 1n sideelevation; Fig. 2 1s a view in elevation showing a' portion of thecutting means; Fig. 3 is a view taken on line a-a of Fig. 2; Fig. 4 is aview in elevation of the means employed to prevent the cut strips fromlapping one upon anotherf Similar reference characters refer to similarparts throughout the several views of the drawing.

Referring now. to the drawing, wherein I have shown a preferredadaptation of my invention, 1 denotes 1 of the two oppositelydisposedsides of the framework of the machinein which are supported the severaloperative parts'thereof embodied in my invention. In the rear portion ofthe framework is journaled a roller 2 upon which is supported the rollof web 3 which is to be cut into strips. This roller is adapted .to beremovably inserted in journal-block 4, as I clearly shown in Fig. 1.

' The web first passesbetween rollers '5 and 6 and is drawn thereby fromthe supply roll. Roller 5 is carried upon a. shaft journaled between theside walls of the framework of the machine and the webv is held infrictional contact with said roller by roller 6 which is carried by arms7 extending from a shaft 8 journaled between the side walls'of themachine, said shaft being provided with a handle 9 by means of whichroller fi'may be swung upward from its operative position, as shown inFig. 1,to allow for the ready insertion of the ends of the webtherebetween, as when the supply of web becomes exhaust-- ed from thesupply roller and is replaced bya-fresh roll. Roller 5 is suitablydriven by means of a gear wheel 10, carried upon shaft 11, which mesheswith a gear wheel 12, it in turn meshing with a driving gear 13., theshaft 13' of which carries a pulley 14: which is driven from a suitablesource of power, as by means of a belt 15.

Shafts 16 and 17 are journaled at'either end in the side walls of theframework of the machine and upon these shafts are mountedthe cuttingdevices employed for slitting the web into a plurality of strips. Shaft16 carries a plurality of relatively fixed knives 18, these knives beingmade adjustable thereon, so that they may be spaced apart at difiere'ntdistances and secured in any adjusted position by means of set screws 19to admit of the cutting of strips of different widths: and with knives18 c0-act knives 20 carried upon shaft 17. Shaft 17 is provided with akey-way, as'at 21, to receive set screws 21 of knives 20, said setscrews being loosely received in said keyway to permit of knives 20being withdrawn from knives 18, as when a fresh strip of webbing isthreaded through the machine, and these loosely mounted knives are heldresiliently in position to co-act with knives 18 to cut the webbing bymeans of extensile springs 22 extending between collars 23, fixed uponshaft 17 and said knives. Shafts 16 and 17 are provided withinterineshing gears 24 and 25 respectively, gear 24 being ing theportion of the web being fed past the cutting devices.

Meshing with gear wheel 12 is a gear wheel 28 carried upon a shaft 29journaled' between the side walls of the framework, and upon this shaftis mounted a roller 30.

' Gear wheel 28 drives gear wheel 31 through an intermediateintermeshing gearwheel 32 and upon the shaft 33 of gear wheel 81 ismounted a roller 34 similar to thatnumbered 30' on shaft 29.

Slidably mounted in slots 35 of standards 36 erected upon either side ofthe framework of the machine is a rewinding or accumulating roller 37for the cut strips of webbing. This roller rests upon rollers 30 and ,34and is adapted to be driven through frictional contact therewith, and asthe windings of the cut strips increase thereon, said roller can slideupwardly in its slots to compensate for the increased circumferencethereof due ..to the superimposed windings of the webbing thereon.

In order that the several rolls of webbing which are being wound u onrewinding roller 37 may be prevented rom being fastened together byreason of the edges of the cut strips lapping one upon another, spreaderroller 38 is loosely mounted between standards 36, one of whichis shownin Fig. 1'. This roller is threaded'from its central portion towardeither end, the threads running in opposite directions so as constantlyto urge the strips one from another and thus provide a slight spacetherebetween. Roller 38 is driven through its peripheral engagement withthe strips of webbing, and by reasonof its being loosely received inslots 35 of standards 36, it is'permitted to have a bodily movement tocompensate for the constantly increasing diameter'of the roll of woundstrips of webbing upon roller-37.

Having thus described the structural features constituing thisembodiment of my invention, the operation thereof, which should be in alarge measure obvious to those skilled in the art to which thisinvention relates, may be described briefly as follows: The webbing isdrawn from the supply roll" by means of rollers 5 and'6 and'passes overidler 26 through the cutting devices, through which it is drawn by meansof, rollers 30 and 34, idler 27 co-acting with idler 26 ,to support thesame during the cutting operation.

Rewinding roller 37 being driven peripherally by means of rollers 30 and34, receives the several cut strips'and as such strips are wound thereonthe rewindingroller moves upward in its slots to compensate for itsincreased diameter while the frictional engagement between the cutstrips and said driving rollers insures the-passing of the web? bingthrough the machine at a uniform vethe seyeral objects and ends of myinvenother and may readily be separated when'removed from the rewindingroller.

It-will accordingly be seen that I have provided mechanism well adaptedto, attain tion, and that such mechanism is characterized by simplicityand efiiciency.

As many changes could be made in the above construction. and manyapparently widely different embodiments of my invention could be'madewithout departing from the scope thereof, I intend that all mattercontained in the above description or shown in the accompanying drawingshall be interpreted as illustrative andfnot in a limiting sense.

Having described my invention, what I claim as new and desire tosecureby Letters Patent is:
